Outlooks Setup Wizard will not prompt for password when setting up an email account if the PC is joined to the Samba domain.

"Your Name" will be obtained from the "Display Name" field in Active directory and the "E-Mail Address" will be obtained form the "mail" field in Active Directory.

Workaround : When adding an email account, in the "Auto Account Setup" wizard, edit the "E-Mail Address" field and change a character, the password prompt will now be available for you to supply the password.
